Boshart FIN1429-130 1" x 1/2" PVC Insulating Coupling

The Boshart FIN1429-130 is a 1" x 1/2" PVC insulating coupling built for rough-in plumbing installations where a dielectric break is needed between dissimilar pipe materials or between sections of a piping run. Molded from PVC, this reducing coupling steps a 1" line down to 1/2", letting installers transition line sizes while isolating the connection electrically. It is intended for behind-the-wall and under-slab plumbing work, not decorative or finish-grade fixture connections, and is sized to standard 1" x 1/2" trade dimensions so it drops into existing PVC rough-in layouts without custom fabrication.

Key Features

  • Trade Size: 1" x 1/2" reducing configuration for stepping down line size in a rough-in run.
  • Durable Construction: Molded PVC body resists corrosion and is lightweight for fast handling on the jobsite.
  • Insulating Design: Configured as an insulating (dielectric) coupling to break continuity between connected piping sections.
  • Reducing Fitting: Combines a size transition and an insulating break in a single fitting, reducing the number of connections needed in a run.
  • Rough-In Ready: Sized and configured for use behind walls, under floors, or in other concealed plumbing assemblies where a plumber or contractor is completing supply or drain runs.

Technical Specifications

  • Trade Size: 1" x 1/2"
  • Product Material: PVC
  • Product Type: Insulating Coupling
  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Residential and Commercial Rough-In Plumbing
  • Reducing Transitions in PVC Piping Runs
  • Dielectric Isolation Between Piping Sections
  • New Construction and Renovation Plumbing Work
  • Behind-the-Wall and Under-Slab Installations

Boshart FIN1429-130 – Frequently Asked Questions

1) What does the Boshart FIN1429-130 insulating coupling actually do in a piping run?
It does two jobs in one fitting: it steps a 1 inch line down to 1/2 inch and it breaks electrical continuity between the two connected sections. That dielectric break is what keeps dissimilar pipe materials from being electrically bonded through the joint. Using it saves you stacking a separate reducer and a separate insulating fitting in the same run.
2) Will the Boshart FIN1429-130 fit my 1 inch PVC line?
One end takes 1 inch and the other 1/2 inch, so it lands in a 1 inch run where you need to drop to a 1/2 inch branch. If both ends of your run are the same size, this reducing coupling is the wrong part and you want a straight 1 inch insulating coupling instead.
3) Can I use this coupling where a copper line meets a different pipe material?
That is the case it is built for. The FIN1429-130 is configured as an insulating (dielectric) coupling to break continuity between dissimilar pipe materials or between sections of a run, while also reducing from 1 inch to 1/2 inch at the same joint.
4) What material is the Boshart FIN1429-130 coupling made from, and how does that affect where I can use it?
Molded PVC. That makes it corrosion resistant and light to handle, and it is the reason it provides the insulating break, since the plastic body won't carry continuity between the joined sections. It is sized to standard 1 inch x 1/2 inch trade dimensions, so it drops into an existing PVC rough-in layout without custom fabrication.
5) What is the exact Boshart part number for the 1 inch by 1/2 inch PVC insulating coupling?
FIN1429-130 from Boshart. That is the single model sold under this name, so there are no finish or configuration options to specify when ordering.
